Cake Batter Chocolate Sandwich Cookies

With their cake batter filling and crunchy chocolate cookies, these cake batter chocolate sandwich cookies are a sweet treat you need in your life!

Before we get to today’s recipe, I need to say THANK YOU from the bottom of my heart to everyone for their kind words about my post last week. I’m so grateful to everyone who commented and emailed in response. Words really can’t express how much I appreciate all of you, and how lucky I feel to have such wonderful people in my life. You all make my every day better!

But now, the main event: cake batter chocolate sandwich cookies. I know you’re here for the baked goods, not the self-indulgent babbling :).

Can I let you in on a little secret? I LOVE cake batter from a box mix.

Generally I prefer to eat a cake made from scratch—not always, but most of the time.

But when it comes to the batter? Well, box batter is just better. To my taste buds anyway. I’m not sure, but I think my preference is a holdover from my college days, when I was known to eat yellow cake batter (from a box) for dinner when I was too lazy to cook.

Yeah. Health nut I am not. If I tried to do that today I’d end up with a month-long migraine, not to mention I’d be shopping for a new wardrobe.

But nothing is stopping me from eating one (or three) of these cake batter chocolate sandwich cookies after a balanced dinner.

Or a balanced breakfast, because some things never change.

These chocolate cake batter sandwich cookies are sort of like a homemade Oreo. The cookies themselves are very crunchy and provide a perfect contrast to the creamy cake batter filling.

And the filling is just a simple buttercream with a couple of tablespoons of yellow cake mix mixed in. Guys, it tastes JUST like the cake mix.

(Duh, Kels, you’re probably thinking. Did you think it would taste like chicken? Well no, silly. But I was concerned I’d need so much cake mix to get a good cake batter flavor that my filling would cease to be fluffy. Fortunately, it didn’t take much.)

The sprinkles in the filling are optional, in the way that they aren’t integral to the cookie. But they’re necessary in the way that sprinkles are integral to a happy life. So include/exclude the sprinkles as you wish.

These heavenly little sandwich cookies are my life right now. Crunchy, creamy, sweet and chocolate-y, they’re my new favorite afternoon snack. And I know they can be yours too!

These chocolate sandwich cookies are like Oreos, but better because they're homemade and taste like cake batter!

1large egg

1 1/2cupsall-purpose flour

3/4cupDutch-processed cocoa powder

1/2teaspoonsalt

1/2teaspoonbaking soda

1/2teaspoonespresso powderoptional

Filling:

1/2cupunsalted butterat room temperature

1 2/3cupspowdered sugarless 1 tablespoon

2tablespoonswhite or yellow cake mix

1/2teaspoonvanilla extract

1tablespoonmilk

1/8teaspoonsalt

3tablespoonsrainbow jimmies

Instructions

Cookies:

Whisk the butter and sugar together in a medium mixing bowl until well combined. Whisk in the vanilla and melted chocolate. Add the egg and whisk until fully combined.

Stir the flour, cocoa powder, salt, baking soda, and espresso powder (if using) together in a second medium bowl. Stir the dry ingredients into the butter-chocolate mixture with a wooden spoon; if the dough is too stiff to mix with the spoon, use your hands. Mix until the dough is cohesive. Let the dough sit at room temperature for 1 hour.

Transfer the dough to a large square of parchment paper and shape into a log about 10 inches long. Wrap the parchment around the log, then roll back and forth on the counter a few times to form a smooth log of dough. Place in refrigerator for at least 2 hours, turning the log every 15 minutes or so to maintain the log’s round shape.

Center a rack in the oven and preheat to 325 degrees. Line two large baking sheets with parchment paper.

Cut the dough into 1/4-inch-thick slices and arrange them on the prepared baking sheets 1 inch apart. Bake for 18 to 23 minutes, just until cookies are firm to the touch. Cool cookies completely on the baking sheets before filling.

Filling:

Place the butter in the bowl of a stand mixer fitted with the paddle attachment. Beat on low speed until very smooth, about 30 seconds. Beat in the powdered sugar, cake mix, vanilla, milk, and salt and mix until mixture is very smooth. Fold in the rainbow jimmies with a rubber spatula.

Scoop 1 heaping tablespoon of filling onto half of the cookies. Top with remaining cookies, then press down to flatten the filling. Serve and enjoy.

Cake mix in the frosting? Say what!? That is nothing short of genius! What a fun idea! And those chocolate cookies look amazing, too, Kelsie. I’m pretty sure I need to just move in next door so I can sample all of these delicious treats that you keep posting. Although I’m not sure I could handle that Phoenix heat. My blood has thickened since we’ve moved up north. (Did I mention we’re hitting the 40’s at night now? Maybe you should move this way instead…and still share your delicious treats with me. Haha!) I’m going to have daydreams about frosting with cake mix in it all day today now. 🙂 Have a great long weekend, my friend!

These are so pretty Kelsie. Just (almost) too pretty to eat, but I’m not that cray cray NOT to eat ’em 😉 Sprinkles optional? Nope. No way girlfriend 🙂 Gotta have those cause they are just too darn fun! Have an awesome weekend!

These are screaming my son’s name. I usually poach on his ice-cream cookie sandwiches. Must have the sprinkles:) I will not worry about you over the long weekend, you will have plenty of treats I think:)

I had to pop over here immediately for the recipe when I spotted these on your Instagram! They look just incredibly delicious. I love that filling and I bet these cookies would be awesome for ice cream sandwiches too!

What?! Cake batter for dinner? Now I’ve heard it all, haha!! But those collage days were the good old days, weren’t they? These sandwich cookies are adorable, and I love the cake batter filling! It’s such a clever (and delicious) idea,Kelsie!!

I definitely think we must be some sort of long lost cake batter loving relatives. I didn’t know I needed these in my life but now I am certain I can’t live without them. I love the cake batter buttercream idea!

Wow! These look amazing, and sound amazing! Not sure I can resist… I do have a box mix in my pantry. And what is it about that batter that tastes so yummy? I agree with you that it is tasty, but I really want too understand what it is that makes it so. ?

Haha..Im with you, I could drink the cake batter made from a box mix!! These sandwich cookies just make me want to smile (and eat them). They are so pretty and I love chocolate brown with bright pops of sprinkle color. Take care.

What?! Kelsie, the Queen of Cheesecakes, Brownies, and Cookies, LOVES cake batter from a box mix? I’m shocked! I need something delicious to get over this horrible fact:) What about these tasty cookies? I’d like some with a dulce de leche filling (just cause I love dulce de leche). Nice work!
